10. Earnings per Share

Basic earnings per common share (“EPS”) is computed by dividing net income attributable to the common shareholders of the Company by the weighted-average number of common shares outstanding. Diluted EPS is computed in the same manner as basic EPS, except the number of shares is increased to include additional common shares that would have been outstanding if potential common shares with a dilutive effect had been issued. Potential common shares consist primarily of stock options and restricted performance shares calculated using the treasury stock method.

The calculation for basic and diluted EPS is as follows:

We have certain stock options and restricted performance shares that are potentially excluded from the computation of diluted EPS. The effect of the potential exercise of stock options is excluded when the average market price of our common stock is lower than the exercise price of the related option during the period or when a net loss exists because the effect would have been antidilutive. Additionally, restricted performance shares are excluded because the necessary vesting conditions had not been met or when a net loss exists. As of December 31, 2023, 2022 and 2021, there wereno stock options excluded. Restricted performance shares outstanding of 0.7 million as of December 31, 2023,0.6 million as of December 31, 2022 and 0.5 million as of December 31, 2021, respectively, were excl uded.
